Most places won't let you open the package.
I wanted to open the package of a pelican PSP power adapter to look at the volt/amp output at Best buy, but I was told to purchase it first, open it, then return it if it didn't work.
When I got it home, I was glad it was the same as the one recommended here on the forums.
I found one more dongle, this one may work. I added it to my post above.
Is there a website that identifies the chipsets in these ethernet dongles, or where online can one find such info?
